HVAC Troubleshooting Guide

You can have top-rated HVAC units and still experience issues. In this HVAC troubleshooting guide, we discuss the most common HVAC issues and how to approach them.

Indoor Air Quality Issues

No smog allowed. When you’re breathing the same recycled air day in and day out, you want it to be good quality, clean, and clear. Letting a little fresh air into your facility by opening the windows (if possible) on nice days is one way to boost your indoor air quality. Keeping up with changing the air filters on your HVAC system is another way. This should be a regular part of your HVAC maintenance checklist, so consult your HVAC manual or call an HVAC technician to determine how often you need to change or clean your filters.

Sluggish Startup

Ignition problems can give you a difficult time when you’re starting your HVAC system. When troubleshooting your HVAC system for ignition problems, checking igniters and pilot lights are a good starting point. Make sure there aren’t any drafts from open windows causing problems with the pilot light. If that doesn’t help, you should contact a professional to check for any clogs or electrical problems to make sure your ignition problems aren’t a sign of something more serious.

Thermostat Problems

Has your HVAC system shut down completely? Is the temperature not working according to your plan? These issues can both be tied to issues with the thermostat. Start by making sure it’s on, and the batteries are in good working order. Then, ensure you have your thermostat programmed to control the temperature in your facility for optimal comfort.Has your HVAC system shut down completely?

Uneven Cooling

Have you experienced perfectly cool rooms in one part of your facility and stuffy areas in others? This could be a sign of leaky ducts or other sealing issues that allow the cool air to seep outside the facility instead of efficiently cooling the entire space.

Check all air vents to make sure they’re open. Check to make sure the vents aren’t blocked, and check the filter – clogged filters can create uneven heating and cooling patterns.

If you’re still experiencing issues, an experienced pro can troubleshoot your HVAC system to pinpoint and fix the problem. They can provide an HVAC duct size calculator to make sure your ducts are sized correctly, seal up potential leaks and replace ducts as needed, and evaluate HVAC fans and blowers for potential problems.
